Exception pasting rows

I have a data bound grid. I use GridModelCutPaste.Paste to paste a row I just copied. I set EnableAddNew to true. If I try to paste to the last row (the fake one used to add record), I get an exception. If I paste to a real row, it works fine.

If you want to append rows dusing a paste, you will have to handle this your self. One way is to subscribe to the PasteCellText and add the row there is needed.
//subscribe to the event
this.gridDataBoundGrid1.Model.PasteCellText += new GridPasteCellTextEventHandler(Model_PasteCellText);

//the handler
private void Model_PasteCellText(object sender, GridPasteCellTextEventArgs e)
{
	if(e.ColIndex > this.gridDataBoundGrid1.Model.ColCount)
		e.Cancel = true;
	else if(e.RowIndex == this.gridDataBoundGrid1.Model.RowCount)
	{
		CurrencyManager cm = this.gridDataBoundGrid1.BindingContext[this.gridDataBoundGrid1.DataSource, 
			                                    this.gridDataBoundGrid1.DataMember] as CurrencyManager;
		cm.AddNew();
	}
	else if(e.RowIndex >= this.gridDataBoundGrid1.Model.RowCount)
		e.Cancel = true;
}
